SAWING MACHINE.

SPECIFICATION forming part of Letters Patent N0. 501,826, dated July 18,1893.

application filed March 2, 1893. Serial No. 464,364. (No model.)

To all whom it may concern.-

Be it known that I, LYMAN COOPER, a citizen 0f the United States ofAmerica, residing at Patoka, in the county of Gibson and State ofIndiana, have invented certain .new and useful Improvements inSawing-Machines; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specification.

The object of this invention is to provide a sawing machine which ischeap and simple in construction, and in whichthe parts can be adjustedso that the saw may be operated to out either vertically orhorizontally; and the invention consists in the construction andcombination of the parts, as will be hereinafter fully-set forth andparticularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a sawingmachine constructed in accordance with my invention. Fig. 2 is a rearelevation. Fig. 3 is a plan view. Figs. 4: and 5 are detail views.

A designates a suitable base to which are rigidly secured uprights B andB, connected at their upper ends by a cross-piece as shown. To theseuprights are attached bearings in which are j ournaled shafts O and D,the shaft D having mounted thereon a fly-wheel d, which may also be usedas a supporting wheel in transporting the device from place to place,and when so used the set-screw d is loosened so that the wheel can turnfreely upon the shaft. The shafts O and D are pro- Vided with pulleys,as shown, over which passes a driving belt, the shaft 0 having asuitable crank-handle to provide for turning the same. The upright B iscut away or recessed on each side above and below the shaft D. Withintwo of these recesses, so as to embrace the upright, is secured abracket-arm E, the outer end of which is bifurcated to receive the endof a slotted bar F, upon which the slide G which carries the saw ismounted. This bar is pivotally secured to the bracket, and to the outerend of the same is attached a flexible connection which extends over .apulley journale'd near the upper end of the upright B,'the free end ofthe flexible connection or cord carrying a weight w.

H designates the saw, which is attached to the slide G in any suitablemanner. The slide is provided with an aperture on the same side as thesaw, to provide for the attachment of the pitman-rod I, and on one sideat right angles with the saw with another aperture to receive the pin 1'of the. pitman when the position of the saw is changed from a verticalto a horizontal position. The other end of the pitman-rod is connectedto a crank-arm carried by the shaft D. The pitman-rod may bedisconnected from the slide G, and the bar F carrying said slide can begiven a quarter turn in the bracket-arm E, so that the angle of the sawmay be changed. The height of the saw can be changed by adjusting theblock E upon the upright B.

The bar F is provided with a longitudinal slot, and the slide G ispreferably made up of four pieces rigidly connected to each other, oneof which lies in the slot while the others embrace the side of the bar.

When the device is used for felling trees one corner of the same ispivoted to the ground by a pin K, and the forward portion of the basemay be placed upon a plank or board L, which 'is held in place by theWeight of the machine and a pin Z. One of the side pieces of the base isprovided with a flat spring M, the free end of which is placed againstthe pin Z and the machine swung upon the pivot, so that when the saw isin engagement with the tree the tendency of the spring will be toconstantly move the saw against the tree and aid in sawing.

I am aware that prior to my invention it has'been proposed to provide ahand-sawing machine with a supporting frame and mechanism forreciprocating a saw, and I do not claim such as my invention; but

What I do claim as new, and desire to secure by Letters Patent, is-
